Hanna Herde (Brandeis U.) “Measuring the Mass of the Higgs Boson in the Four-Lepton Final State with the ATLAS Detector”

January 7, 2020 @ 4:00 pm - 5:00 pm

The Higgs boson mass determines its couplings to every other known particle – and it is a free parameter of the Standard Model of Particle Physics.  Understanding the Higgs’ connections with the rest of the universe requires measuring its mass experimentally. This talk presents the mass measurement in the four-lepton final state with the ATLAS detector using the full LHC Run 2 proton-proton dataset of 139 \fb at \sqrt{s}=13 TeV. It will particularly emphasize the role of the detector  and include a look at ATLAS’ future in the High Luminosity era  – the Phase II Inner Tracker upgrade.
